How the practice test is scored
A correct answer earns one point and a wrong or blank answer earns nothing, as on the real exam, so it always pays to answer. The result is the number correct and the percentage. The multiple-choice section is 50% of the AP score; the rest comes from free response, which is not simulated here, so no AP score of 1 to 5 is shown.
